set Child`s Id to parent of parent`s unique id in Vanilla Javascript in Firebase blog
I am creating a blog. In my loadBlog function I am creating a div, which gets a unique id for every single loaded blog post: div.id = newPost.postID;
In this div's div I have a button embedded, what I would like to achieve is when I enter editing mode (where I can edit and delete posts) the button to get the parent of parent`s id with an attached string + "delete".
E.g
div id=postId-0
set the delete button's
button id=postId-0-delete
function enterEditingMode() {
document.getElementsByClassName('admin-help-editing-hidden')[0].classList.toggle('admin-help-editing');
let button = document.getElementById('editing-mode-button');
if (button.innerHTML === "Editing mode") {
button.innerHTML = "Exit editing mode";
const parentObject = document.getElementsByClassName('post-title');
[...parentObject].forEach((parent, i) => {
let addDeleteButton = document.createElement('button');
addDeleteButton.innerHTML = "Delete";
addDeleteButton.setAttribute("onclick", "deletePost()");
addDeleteButton.id = //how to set dinamic id
addDeleteButton.className = "delete-button";
parent.appendChild(addDeleteButton);
})
}
else if (button.innerHTML === "Exit editing mode") {
...
}
}
}
function loadMyBlog() {
let posts = firebase.database().ref('posts/');
posts.on('child_added', function(snapshot) {
let newPost = snapshot.val();
let div = document.createElement('div');
div.className = 'blog-post';
div.id = newPost.postID;
....}

I have figured it out myself. The reason why I could't get it because when I was trying to add addDeleteButton.id. it didn't actually exist in the DOM yet. That is why I could't get parent's ID. I had to appendChild(addEditButton) first and then
addDeleteButton.id = addDeleteButton.parentNode.parentNode.id + "-delete";
